Spring-Loaded Mechanism of DNA Unwinding by Heptitis C Virus NS3 Helicase

NS3 is an essential helicase for replication of Hepatitis C virus, and is a model enzyme for investigating helicase function. Using single molecule fluorescence analysis, we show that NS3 unwinds DNA in discrete steps of approximately 3-bp. Dwell time analysis indicates that about three hidden steps...
